The debate around immigration is often markedly different in London to the rest of the country. For instance, the latest report from UCL suggests rejecting Europe and migrants could be economically damanging, whereas in other parts of the country, anti-EU policies and calls for tighter border controls are increasingly popular, as evinced by the recent successes of UKIP.

Joe Watts talks about how Westminster is approaching the matter, why immigration dominates the political discourse and why this is disappointing not only to London, but for the wider population too - and why it facilitates UKIP's influence.

Joe also explains why the difficulties with migration are more than economic and why the very heart of the matter is, for many people, the social impact migrants have.
